Be it known that I, FREDERICK WV. Moons, a citizen of the UnitedStates,residing in Lynn, y in the county of Essex and State ofMassachusetts, have invented an Improvement in Apparatus for FormingDesigns on Opposite Surfaces of a Sheet of Fibrous Material, of whichthe following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

This invention relates to an apparatus by means of which a flexiblesheet or layer of fibrous material may have the same design formed onits opposite surfaces. For this purpose I employ a belt-knifesplitting-machine of any usual or suitable construction and adjust thegage-roll with relation to the ring-roll of said machine so as to allowof the passage between them of the flexible sheet or layer and a patternprovided with solid portions and with spaces or openings between saidsolid portions which cooperate with said machine to form the design onboth surfaces of the said sheet or layer.

Other features of this invention will be pointed out in the claims atthe end of this specification.

igure 1 represents a suflicient portion of a skin provided with a designwhich is formed thereon by an apparatus embodying this invention; Fig.2, a sectional view of a sufficient portion of an apparatus embodyingthis invention; Figs. 3, 4:, 5, and 6, details in section to be referredto, and Figs. 7 and 8 modifications to be referred to.

Referring to Fig. 2, I have represented the essential elements of abelt-knife splittingmachine, which may be of any suitable or usualconstruction and which is employed to form a design a on the upper andlower surfaces of a skin or other flexible sheet or layer 1) of fibrousmaterial.

The essential elements of the belt-knife splitting-machine herein shownconsist of the bedroll a, the ring-roll (Z, the gage-roll 0, the presserroll f, and the belt or band knife g. The mechanism for impartingmovement to the knife g and the rolls of the splitting-machine is notshown, as such mechanism is well known. The gage-rolle and ring-roll (Zhave cooperating with them a pattern 5, which is fed between said rollswhile bearing on the upper surface of the skin I), which preferablyrests upon a yielding backing a, of paper or other like material.

l l l The pattern 1? consists of a strip or sheet of suitable material,such as celluloid or metal, which is provided, as shown in Figs. 2 and5), with solid portions in the form of projections j and with spaces oropenings k, into which portions of the skin are forced to form a design,which is in relief with relation to the portions of the skin compressedby the solid portions j of the pattern. The presser-roll f and gage-rolle are adjusted with relation to the ring-roll (Z so as to affordsufficient space for the passage of the pattern "i, the skin I), andpreferably also the sheet a of paper or like yielding material, as willbe described. The apparatus may be provided with the usual rigid tableI.

In operation with the apparatus herein represented the skin 5 and theyielding backing n are subjected to compression as they are fed betweenthe rolls (6 together with the pattern '1', the projections j of whichengage the upper surface of the skin. The projec tions j force certainportions of the skin below other portions of the upper surface of theskin, which other portions enter the spaces or openings in the patternand are substantially uncompressed, and simultaneously the projections jforce certain portions of the lower surface below or beyond the plane ofthe lower surface and into the path or plane of the movable knife andthose portions of the skin which project below or beyond the lowersurface of the skin are removed or cut off by the knife 9, therebyforming on the lower surface of the skin the same design which is formedby compression on the upper surface of the skin, so that when thecompression is removed, which occurs when the skin has passed throughthe machine, the skin is provided with the same design on both surfaces.

The operation of the machine may be clearly understood by reference toFigs. 3 to 6. In Fig. 3 the pattern 1', the skin I), and the backing 'nare represented in the normal or uncompressed position before passingthrough the rolls.

In Fig. at the parts represented in Fig. 3 are shown in the positionthey occupy while passing between the gage-roll 0 and the ring-roll (Z,and when in this position the projections j on the pattern i are forcedinto the upper surface of the skin I), and corresponding portions 0 ofthe skin are forced beyond the level of the lower surface of the skinand into the yielding backing.

In Fig. 5 the projecting portions 0 of the lower surface are representedas being cut by the knife g, and in Fig. 6 is represented the skin afterit has passed through the machine.

he skin on its passage between the rolls 6 (Z is subjected to pressureover its entire surface; but the portions which are engaged by theprojections j on the pattern are subjected togreater pressure than theportions of the In Fig. 6, 10 represents the uncompressed portions ofthe upper surface of the skin, and athe compressed portions. Theportions which are removed from the lower surface 9 of the skin arerepresented by r.

It will be observed that the uncompressed portions 12, which enter thespaces or openings k in the pattern, form on the upper surface of theskin a design which is in relief with relation to the compressedportions a and that the portions 9 of the lower surface also form adesign in relief with relation to the removed or cut portions 0 of saidlower surface, and this deslgn is the same as that formed by theuncompressed portions 0.

The pattern 2' may be made in the form of a sheet or strip, which islaid upon the skin pressed portions of the skin, as represented in Fig.7 In this case the parts of the skin which are engaged by the solidportions of the pattern are forced below the level of the knife and areout to form the design on the lower surface of the skin.

In the pattern shown in Fig. 7 the solid portions 71 correspond'to theprojections 7' of the pattern shown in Fig. 2, while the openings .9correspond to the spaces Z4.

- In the machine herein shown the gage-roll e and the ring-roll a formcompression rolls or devices which hold the skin firmly undercompression while beingcut by the knife, and

while I prefer to make the pattern separate from the gage-roll I do notdesire to limit my ormed on the invention in this respect, as thepattern may the gage-roll e as represented portions, said solid portionsof the pattern being acted upon by the gage-roll to compress portions ofa sheet or layer of fibrous material below the cutting edge of saidknife to cause said knife to remove portions of said fibrous sheet orlayer and form on one surface thereof a design composed of a pluralityof component parts corresponding to the design other surface by thesolid porpattern, substantially as det1ons of said scribed.

2. In a machine of the character described, compression-rolls betweenwhich the sheet or layer of fibrous material is fed, a pattern providedwith solid portions and with spaces or openings between said solidportions movable with one of said rolls and engaging one surface of saidsheet, and a knife cooperating with said compression-rolls to act onsaid sheet and remove a portion thereof while firmly held undercompression bysaid rolls, substantially as described.

3. In a machine of the character described, in combination, compressiondevices between which a sheet or layer of fibrous material is fed, apattern provided with solid portions and with spaces or openings betweensaid solid portions movable with one of said devices and engaging onesurface of said sheet to form a design thereon composed of a pluralityof component parts, and to simultaneously form proopposite surface ofsaid sheet,

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
